Abstract

PURPOSE: To prevent an operation of overshoot caused by overintegration, by a method of control to select an integral function to a signal source side, working on the basis of effective head, until a rotation of water wheel reaches the rated speed of rotation, when operated a starting of the water wheel.
CONSTITUTION: When operated a starting of water wheel, a deviation signal of "Speed-up" of rotation will be inputted to a PID amplifier unit 6 until the rotation reaches the rated speed, with the processed control signal driving an auxiliary servo motor not shown in the drawing. An input signal at this time to an integrating amplifier 6b comes to be one at the side of multiplier 26 through a normally close contact 29b. The signal at this time, as an opening angle of guide vane for no load changes inversely proportional to an effective head, will be made correction in a divider 23 and the multiplier 26. That is, an output of rated head setter 22 is divided by an output of head converter 21, with that output multiplied in the multiplier 26 as the set signal of guide vane opening angle setter 25. The control will be operated, at the time of starting, so as to provide the same absolute value of outputs from the multiplier 26 and the integrating amplifier 6b
